Which microscope is often used to view metal surfaces

2 answers:

3 0

<span>The question is which microscope is often use to view metal. The answer is scanning tunneling microscope. It is a high resolution microscope which uses neither light nor electron beam but it has very fine tip which has the ability to reveal the atomic and molecular details of metals. It was developed in 1981 by Gerd Binnig and Heinrich Rohrer.</span>

The correct option is:

B. scanning tunneling microscope

Explanation:

A scanning tunneling microscope is an instrument for imaging surfaces at the atomic level. Its expansion in 1981 introduced its inventors, Gerd Binnig and Heinrich Rohrer, the Nobel Prize in Physics in 1986. The scanning tunneling microscope (STM) is a type of electron microscope that shows three-dimensional images of a sample. In the STM, the structure of a surface is considered using a graver that scans the surface at a set distance from it. A remarkably fine conducting probe is held near to the sample.

Explain the difference between afferent and efferent neurons.

natka813 [3]

Answer:

<h3>The Difference between Afferent and Efferent Neurons :- </h3>

Neurons that receive information from our sensory organs (e.g. eye, skin) and transmit this input to the central nervous system are called afferent neurons.

Neurons that send impulses from the central nervous system to your limbs and organs are called efferent neurons.

In which group is parthenogenesis a normal event?

bezimeni [28]

Answer:

Bees

Explanation:

Parthenogenesis is a method of asexual reproduction in which an egg cell develops into a new individual without fertilization. Parthenogenesis occurs in insects, amphibians, reptiles, fish, and in some plants. Most of the organisms which reproduces through parthenogenesis, they also reproduce sexually. Parthenogenesis may be occurs by apomixis and by automixis. In apomixis, egg is produced by mitosis and results into diploid clones. In automixis egg is produced by meiosis and the haploid egg develops into diploid new individual by the duplication of chromosomes. Parthenogenesis is an adaptation which allows to reproduce in adverse environmental conditions when sexual reproduction is not possible.

Students in a science class were asked to investigate how missing or damaged organelles affect cellular homeostasis for cells fo

lora16 [44]

Answer:

B. At what rate do the mitochondria of the cell need to convert glucose to usable energy molecules to meet the high energy needs of the cell?

Explanation:

Organelles are specific in their functioning and hence, each organelle contributes its own quota to the cell's proper functioning. According to the question, a muscle tissue is being worked on to determine the effect of a missing or damaged organelle on its cell.

Mitochondria are organelles found in all eukaryotic living cells. They are the organelles responsible for the synthesis of ATP (energy) used by the cell as a result of the glucose that gets converted in them during cellular respiration.

Therefore, to determine if the muscle cells are functioning properly, the question that: At what rate do the mitochondria of the cell need to convert glucose to usable energy molecules to meet the high energy needs of the cell? should be asked.

Note that, Chloroplast and cell wall are not found in muscle cells, which is an animal cell. Likewise, ribosomes are not organelles for synthesis of glucose.
